RELIABLE VFD HANDLE PANELS FOR IMPROVED INDUSTRIAL MOTOR PACE OPTIMIZATION

For example, with an average 480 VAC 3-period enter voltage, the DC bus will keep a demand of about 650 VDC, with precise bus voltage according to the line voltage degree and motor load. The main reason the DC bus voltage is increased than the nominal enter line voltage is due to the root-imply-squared measurements of AC sine waves (the “peaks”
